Lipoatrophy?

About 2 1/2 years ago I had lost my virginity to a women of unknown status. It was protected sex and when it was done--I noticed that i had developed some grazes on the base of the penis that was not covered by the condom. It was not bleeding or it did not present any blood in anyway. However, two years after this incident I started developing fat loss in my legs and buttocks area. Some in the face but noticeable to others. Every since I was a kid--I had always had digestive problems and now growling almost everynight before I go to bed. I don't want to get into all the symptoms. About a month ago I got low wbc count--low neutrophils count. I decided to read up on HIV. After just doing some searches on HIV I accidentally ran into Lipoatrophy pictures and it freaked me out because I have always wondered what he causes of this fat loss in my legs and buttocks was. I have seen my friends do some nasty **** and I have never participated in any of their careless sexual lifestyles. I never thought that I need to test and now I am scared to test.
1) Am I at risk?
2) Can lipoatrophy be caused by HIV itself? Or it is side-effect of medication?
3) Is there any other conditions that may cause lipoatrophy?

No you were never at risk. See your doctor for you symptoms it has nothing to do with HIV.

I am a little confused with your question, you say you had protected sex? And the condom did not fail? If you had protected sex the situation, which you described is not a risk, however if the condom had failed you may need to test just to be on the safe side.
